I Got Bit By A Spider Two Days Ago I

I got bit by a spider two days ago I didn’t know that I had got bit until after I had scratched all the skin off of that area and it’s really redit’s not hurting anymore it’s just bright red around the infected area When I went over my friends house I saw the spiderweb on the porch and that’s how I knew I had got bit by something while standing on her porch
